UPDATE 2019-10-31: Uploaded v2.1 of the hotend carriage (thicker, with nut catches for mount points and taller belt catch slots), a 4.5mm tall riser for the Creality hotend, and a printable tool you can use with 15mm M3 bolts to perfectly square the nuts in their catches before supergluing them. I've been running this for a few days now, and it's incredibly rigid. Quite happy with this design as it sits.

UPDATE 2019-10-22: Uploaded v2.1 of the gantry carriages to account for different screws in the bearing assembly, as mine had pan-head screws and wouldn't fit...

This is an all-inclusive rail system for the Ender 5 and Ender 5 Plus. I collaborated with drewshipley on this who collaborated with kmxs, who got it from who knows where.

There are two versions: normal and raised bed. If you choose to go with the raised bed, you will need the 25mm Z-Stop for the Ender 5 or 4 of the Bed Risers for the Ender 5 Plus(you will also LOSE 25mm on Z, and this is unavoidable).

For the Ender 5, you need 3x 350mm MGN12 rails, 3x MGN12H bearings, 42x M3x8mm bolts, 42x M3 T-Nuts, 2x M4x8mm bolts and 2x M4 T-Nuts (normal). To use the RAISED version, add 4x M5x45mm bolts

For the Ender 5 Plus, you need 3x 450mm MGN12 rails, 3x MGN12H bearings, 66x M3x8mm bolts, and 66x M3 T-Nuts (normal). To use the RAISED version, add 4x M5x45mm bolts, 8x M4x8mm bolts and 8x M4 T-Nuts for the bed risers.
